Triad InRoom PowerSub Review

Adding Triad's InRoom Gold PowerSub completed the sound stage of the MinMonitors as it provided the remaining bass that the bookshelf speakers alone could not produce. The Triad InRoom Gold PowerSub implements a 15" woofer and a 250 watt amplifier in large square cabinet. Reverting to the "small" setting for the front channel and blending the PowerSub with a cutoff frequency of 80-Hz balanced everything out and created the ambiance of a much larger speaker system. Once I adjusted the PowerSub volume using my Sound-level Meter, I focused on setting the phase correctly for the environment of my audition. Triad made this job much easier by including avariable phase adjustment on the back of the sub. I connected the PowerSub two ways, the first being the "Theater Input" and the second being the "Left and Right" inputs. Left & right channel inputs have volume controls for deep frequency extension, and the mono "Theater Input" has a fixed gain configured for highest output from 40 to 80 Hz. If you plan on using the speaker system for music and movies, than the "Left and Right" inputs may be the preferred choice.

Editorial Note
According to Triad, using the LEFT and RIGHT inputs, the response is EQ'ed almost flat to 20 Hz while the THEATER input is down 3 dB @ 35 Hz, and is not usually recommended.

It would have been nice if Triad had included speaker level inputs to appease the 2-channel audiophites who do not prefer or have line level input connectability.  If I were to purchase these speakers as a part of a 2-channel analog stereo system I would likely have used the speaker level connections and PowerSubs internal crossover for my configuration.

My only adverse comment about the PowerSub is its overall size when utilized with the MiniMonitors.  My feeling is that most people looking to purchase bookshelf speakers are doing it because of the Wife Acceptance Factor or a lack of room for floor standing tower speakers.  That being the case, it's hard to justify the presence of a large cabinet PowerSub.  But based on the soundstage created by the MiniMonitors and Gold Sub, it may be worth the sacrifice of aesthetics and real-estate in order to achieve sonic Nirvana.
